Abstract
Description
- 1) A polarizing film based on PVA film and absorbed iodine or dichroic dyes;
- 2) A polarizing film obtained by subjecting a polyvinyl alcohol-type film to a dehydration treatment to form a polyene, and orienting the treated film substantially in one direction;
- 3) A polarizing film based on a hydrophobic polymer film and water-insoluble dichroic dyes;
- 4) A polarizing film based on a liquid crystal polymer (LCP) film and water-insoluble dichroic dyes.
